Transfer chicken to clean plate, letting excess marinade drip back into bowl. Discard marinade. Place chicken on grill, top side down. Cover grill; cook 5 minutes, then turn 90 degrees and cook 2 to 3 more minutes, until char marks form. Turn chicken over, and continue to cook 3 to 4 minutes or until instant-read thermometer inserted into thickest part of chicken reads 165° F.
